The invention discloses vertebral column decompression treatment equipment which comprises a base, a machine tool, a connector device, a connector positioning device, a driving device, a geared motor and a control system, wherein the machine tool is arranged at the right side of the base, the driving device and the geared motor arranged on the base are arranged at one side of the machine tool, the control system is arranged at the upsides of the driving device and the geared motor, the connector positioning device is arranged opposite to the left side of the machine tool, the connector device is fixed on the connector positioning device, and the control system is arranged in the base and connected with the driving device and the geared motor. The using method of the vertebral column decompression therapeutic equipment is as follows: under the control of the control system, tensile force exerted by the connector device to a patient is adjusted in a logarithmic tension periodic curve way through the driving device and the geared motor, the tensile force value is fed back and corrected by a tensile force feedback module, then the tensile force is applied to the patient, and finally, the tensile force value is adjusted periodically under the control of a treatment cycle adjusting module for treating patients.
